Nodules-specific assertions for Chai

Installation and usage

$ npm install chai-nodules-helpers

var assert = require('chai').use(require('chai-nodules-helpers')).assert;
 
assert.throwTerror(...);
assert.mixedProperly(...);

Note

All assertions available for assert style only.

Objex

assert.isMixed()

assert.isMixed(Target, Mixin, mixinName, staticExceptions, prototypeExceptions, mixingArgs)

• {Objex} Target – constructor;
• {Function|Object} Mixin – mixin;
• {String} mixinName – used in assertions messages;
• {String[]} staticExceptions – array of statics propertyies names excluded from assertions;
• {String[]} prototypeExceptions – array of prototypes propertyies names excluded from assertions;
• {Array} [mixingArgs] – additional arguments to pass to mixin() after Mixin itself.

assert.canBeMixed()

assert.canBeMixed(Target, Mixin, mixinName, staticExceptions, prototypeExceptions, mixingArgs)

• {Objex} Target – constructor, inheritor of the Objex, mixin method applies to;
• {Function|Object} Mixin – mixin;
• {String} mixinName – used in assertions messages;
• {String[]} staticExceptions – array of statics propertyies names excluded from assertions;
• {String[]} prototypeExceptions – array of prototypes propertyies names excluded from assertions;
• {Array} [mixingArgs] – additional arguments to pass to mixin() after Mixin itself.

Terror

assert.throwTerror()

assert.throwTerror(fn, ErrorClass, spec)

• {Function} fn – a function which expected to throw;
• {Fucntion|Error|Terror} [ErrorClass] – must be a Terror inheritor, if spec is specified, or any Error inheritor in other case;
• {RegExp|String|Number} [spec] – error specifier; can be a string (Terror code name), number (Terror code) or RegExp (used for message test).

If second argument is not a constructor (function), then helper recognize it as an specifier arg spec.
